ABSTRACT:
A universal battery charger including: a housing with a first locating surface; and a slide cover formed corresponding to the housing and having a second locating surface corresponding to and leaning against the first locating surface. The housing is provided with terminal pieces for adjusting the position. The terminal pieces may be moved by fingers from the bottom of the housing. The second locating surface of the slide cover is in tight contact with the first locating surface when the charger is not used, thereby creating a complete contour of the charger without any gaps. In charging, the slide cover is pushed outwards over a certain distance according to the dimensions of batteries such that a charging space is created between the second locating surface and the first locating surface of the housing. The push levers can be pushed by fingers from the bottom cover according to the charging interface of the battery such that the terminal pieces at the platform are moved to a proper position whereby an electric connection with the prearranged batteries is established for the charging purpose. As a result, the universal battery charger of the invention is suitable for all kinds of batteries. Moreover, a convenient adjustment and a practical use are achieved.
